We’re all used to happy go lucky Uncle Dave, wearing his funny, train conductor clothes and saying all kind of cute, yet confusing things about all sorts of stuff. But never in my 32 years years of being a Van Halen fan have I ever seen Uncle Dave get this mad, He doesn’t want people fighting at Van Halen shows and, considering he’s a seventh degree black belt at something or another, I would immediately stop whatever I was doing, should Uncle Dave yell at me.
